Use the decimals 2.47, 9.57, and 7.1 to write two different addition facts and two different subtraction facts

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
